QUINCY – New York City Police Commissioner William Bratton believes local police are up to the challenges of securing Monday’s Boston Marathon.

“They are all prepared for the events over the weekend,” Bratton said at a pre-marathon party Friday night at the Marina Bay home of Boston public relations executive George Regan.

Bratton, who started his law enforcement career as a Boston police officer in 1970 and rose through the ranks to become Boston’s police commissioner, met with the Boston police command staff on Friday.

“They have a very good, coordinated plan,” Bratton said.

More than 3,000 Boston, State and municipal police officers are involved in security for the Boston Marathon. Bratton said the security force includes about 20 New York police officers, including canine teams and officers from intelligence units.

“The idea is just to move on – never forget, but to move on,” Bratton said. “It will go off very well.”

Providing security for the marathon is a much different proposition than it was when he headed the Boston Police Department two decades ago, when crowd control was the major concern, he said.

“Nobody (then) gave a thought to terrorism,” Bratton said. “It’s just an unfortunate reality now.”

He called the marathon one of the world’s singular events.

“At the moment, the good news is that there are no great threats to the marathon, Bratton said.

Bratton and his wife, television legal anyalist Rikki Klieman, were in London for a speech when the marathon bombing took place last year. Klieman said it was the first time she had missed a marathon since 1973.

She said they immediately made plans to attend this year’s running “to support the people of Boston and the spirit of Boston.”

Bratton was introduced by Suffolk County District Attorney Daniel Conley.

“Things changed in our city a year ago,” Conley said. “We came together as a city like never before.”
